Compass/Temp Display

[TeaBag]

I found a person who repairs and upgrades burned out printed circuit boards (PCB) for the GWs and early Cherokees (For those of you looking to get yours repaired.)


He is out of New Jersey and advertises via Ebay. $55 which includes return shipping. You have to ship yours to him, he diagnoses and replaces the bad components, coats the board with a dust/water resistant coating, and sends it back to you.

He claims a 2-3 day turnaround time.

I just put mine in the mail-will let you know how it turns out.n Below is the link to his Ebay post.

Has it been determined that the GW/SJ and XJ parts are the same? The ad does not claim that.

The switches are those little buttons on either side of the display? Interesting that they are still available. I think they mean MLCC is multi-layer ceramic capacitor, a SMD (hard to replace). Typically when stuff like this goes bad it's the electrolytics or mechanicals (switches, connectors). Interesting that they replace all this stuff routinely ... I expect they have identified what goes wrong and replace all that without any testing.

"premium dielectrics"????

Premium INSULATION??? LOL!!!!

And super duper catalytic reverse osmosis electromagnetic shielding and zombie resistant insulation.

It's a thing. https://en.wikipedia.org/wiki/Film_capa ... capacitors

A premium capacitor dielectric would be say styrene, or teflon. Generic is mylar (polyester). But I don't see any plastic film capacitors on that board - there is a MOV - maybe there are some really little ones.

I forgot about caps. I was thinking more of the "conformal" coating that they coat boards with sometimes. GM used some sort of goo like that on their 80s-90s ECMs. It must work. They are still working.

Yes, they are the same. In 1997, they changed the overhead console (including the compass and temp)in the XJ. Prior to that they were the same.
